Flexure hinge optimization
Spatial topology synthesis of large stroke
flexure hinges
Optimization of high performance large stroke flexure hinges:
• Building block based topology synthesis
• Designs evaluated with flexible multibody software SPACAR • Suited for large deflection angles
• Increase in first disturbing frequency of a factor 10 • Optimized design obtained within a few hours
• Results experimentally validated with Nylon prototype
2. Building block approach 1. Introduction
3. Optimized design
4. Achieved results
